Application filed September 28, 1927. Serial No. 222,468.

This invention relates to hair cutting devices and more particularly tomeans for transforming a safety razor into a hair cutting implement.

The principal object of the invention is to provide an attachment to asafety razor which will keep the blade in a certain position so it canbe used for cutting hair.

Another object of the invention is to provide a device of this characterwhich can be readily attached to a safety razor and which can be easilydetached so the razor can be used for shaving purposes.

Other objects will appear as the disclosure progresses. The drawings areintended merely to indicate a possible embodiment of the invention. Itis obvious therefore that the actual needs of manufacture maynecessitate certain mechanical changes. It is therefore not intended tolimit the invention to the embodiment illustrated, but rather to definesuch limits in the appended claims.

For a more detailed understanding of the invention attention is nowcalled to the draw.- ings in which a preferred embodiment is shownillustrated.

Figure 1 is a side view of the attachment showing it applied to a safetyrazor.

Fig. 2 is a front view thereof.

Fig. 3 is a perspective view of the attachment.

Fig. 4 is a front view thereof.

Fig. 5 is a section on line 55 of Fig. 4:.

The safety razor illustrated is that known as an Autostrop to which theattachment is mainly adapted to.

Referring to the drawings in detail 111 which like reference charactersdenote like parts throughout the specification, numeral 1 denotes thesafety razor, 2 the razor blade, and 8 the attachment for positioningthe blade so it can be used for cutting hair.

In razors of this style the shaving position of the blade is that shownin the dot and dash line 4 or when the cutting edge of the blade restsin the end grooves 5.

For forming the razor into a hair cutting device the attachment 2 isplaced on the razor frame as shown in Fig. 1 with the lower edge 6 inthe groove 5 where the edge of the blade rests when used for shaving,and the cutting edge 7 of the blade placed in the grooves 8 of theattachment.

The upper part of the attachment is formed with a curved portion 9 soitwill snugly fit on the holder. Leading outward from the portion 9 area pair of arms 10 and behind the said arms is a cross member 11 forstrength-r ening the device and at the same time forming a lip whichrests in the groove 5 of the razor holder. As noted in Fig. 2 the spacebetween the arms 10 is wide enough for the razor blade to cut the hairin an efficient manner.

It will thus be seen that we have provided an efiicient and simpleattachment for turning a safety razor into a hair cutting device. Theattachment can easily be slipped on and off the razor holder and thusmake the instrument do double service, that of shaving and hair cutting.

Having described our invention, we claim:

1. The combination with a safety razor including a razor blade and arazor frame hav ing a groove, of a blade holding member adapted to besupported at the lower end in said groove and the upper end on saidrazor frame, said blade holding member having a curved portion at thetop for fitting onto said razor frame, a pairof arms extendingoutwardly, the bottom of said arms leading to a cross member, a lipformed in said cross member for fitting into said groove of the razorframe and means in said blade holding member for the positioning of thesaid'blade so it can be used for cutting hair.

2. The combination with a safety razor including a razor blade and razorframe having a groove, of a blade holding member adapted to be supportedat the lower end in said groove and the upper end on said razor frame,said blade holding member having a curved portion at the top for fittingonto said razor frame, a pair of arms extending outwardly from thecurved portion and leading to a cross member, a lip formed in said crossmember for fitting into said groove of the razor frame, a groove formedin said blade holding member for positioning the said blade at a properangle so it can be used for cutting hair.

3. The combination with a safety razor including a razor blade and razorframe having a groove, a blade holding member adapted to be supported atthe lower end in said groove and the upper end on said razor frame,
